Seminal fluids & sperm samples for infertility and post vasectomy analysis

Infertility investigation:

Patients please note: You will need to be provided with a pre-weighed and toxicity tested pot by your GP for your sperm sample, along with a request form signed by your clinician before we can accept your sample for analysis.

Any samples received which are not in a pre-weighed and toxicity tested pot with a signed request form will unfortunately be unsuitable for analysis and will be rejected. The sample pot must have your name and date of birth on it.

Samples for fertility investigation i.e. for sperm morphological assessment, count and motility, should be brought directly to York Teaching Hospital, Laboratory Medicine, Specimen Reception between 8.45am and 3pm Mon-Fri, ideally within 1 hour of production in the toxicity tested sample pot provided by your GP/Clinican. It is important that the time of collection should be clearly indicated on both the form and specimen pot as samples which are examined more than two hours from production are unsuitable for assessing sperm motility.

Directions: On arrival at the York Teaching Hospital Main Entrance, turn immediately right past the Patient Discharge Lounge, then right at the T junction, Sample Reception is 10m down on the left.

Please do NOT bring infertility samples to Scarborough Hospital laboratories as these samples are time sensitive and cannot be analysed at the Scarborough laboratory.

In exceptional circumstances a patient facility can be made available for the production of a sperm sample on-site by prior arrangement only with the laboratory only, please telephone 01904 726332 to make an appointment .
